All I really need to argue is that the initial measure I proposed is
not substantially worse than the implicit measure used by our existing
democracy. But I welcome proposals for improved welfare measures.
We can begin the trial and error you refer to now, if we have the time,
by constructing hypothetical decisions and comparing our intuitions about
the right decision with the choices preferred by various welfare measures.
For example, I proposed summing log(GDP) per each demographic group, but this
leaves open the question of what the zero point is for being dead. That is,
log(0) = negative infinity, so if dead people were taken as having zero GDP,
that would put an infinite weight on avoiding death, which is clearly too
high. I think people tend to put a value of about twice their annual income
on living another year. I'm not sure how to express this in the log
